John Trapp on Proverbs 24:28

Verſ. 28. Be not a witneſſe againſt thy neighbour without cauſe] That is, Without calling, being not thereunto required: for this would ſpeak thee ſpightful, raſh, and revengeful, as in the next verſe.

And deceive not with thy lips] When called to be a Witneſſe, ſpeak thy mind ſimply and plainly, [non-Latin text not transcribed]. without preface or paſſion, without varniſh of fine words, whereby to miſlead the Judge, or deceive the Jurors, to bolſter out a bad cauſe, or out-face a good.
